PROPAGATION DELAY DIFFERENCE REPORTING FOR MULTIPLE COMPONENT CARRIERS

摘要

PROBLEM TO BE SOLVED: To provide methods for reporting on downlink timing by a mobile terminal in a mobile communication system in order to allow an aggregation access point to obtain information on propagation delay differences of downlink transmissions on aggregated serving cells.SOLUTION: The mobile terminal performs measurement regarding transmission and/or reception time differences on a target/reference cell, and reports it to the eNodeB. The eNodeB compares the measurement result to a predefined maximum propagation delay time difference. Alternatively, the mobile terminal performs the measurement, compares it to the predefined maximum propagation delay time difference and then report the comparison result to the eNodeB.SELECTED DRAWING: Figure 36
